BICYCLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 626,239, dated June 6, 1899.

Application filed August 31, 1898.

T0 (tZZ whom, it may concern:

Be it known that I, EDWARD LINDsTRoM, a citizen of the United States, residing at Kenosh'a, in the county of Kenosha and State of Wisconsin, have invented new and useful Improvements in Bicycle-Supports, of which the following is a specification.

My invention relates to improvements in that class of bicyclesupports in which the bicycle is held by a single supporting-rod,which is secured to the frame in such a manner as to fold up against the latter when not in use.

The objects of my invention are, first, to provide an extremely light and durable support which is adapted to be cheaply constructed; second, to so combine the support with the bicycle-frame that it will adequately hold the latter and so that it can be neatly and conveniently folded against the frame when not in use, and, third, to provide a neat and convenient form of lock which will prevent the rod from slipping and aid in supporting the rod in its raised or folded position.

In the following description reference is had to the accompanying drawings, in which- Figure 1 is a side view of a bicycle, showing my invention as it is applied thereto and used for supporting the same. Fig. 2 is a section view showing the joint formed by the supporting-rod with the clamp for securing the same to the bicycle-frame rod and showing also the locking device. Fig. 3 is a cross-sectional view of the cross-bolt of the brace-rod drawn through the eye which receives the locking-bolt.

Like parts are identified by the same reference-letters throughout the several views.

A clamp A is secured to the central or saddle-post rod of the bicycle-frame, the clamping-ears being provided with a reinforcement a ct, which extends backwardly a sufficient distance to be engaged between the clamp and the bicycle-frame rod, a lining of felt or similar material being interposed to prevent marring the latter. \Vith this construction the clamp can be made very light and yet have sufficient strength for the purpose.

The supporting-rod B is made of bicycletubing, reduced or tapered at its free end and provided with a rubber tip 0, which is formed to partially enter the tube. At its upper or at- $eria1No. esatso. (No model.)

tached end the rod B is split and formed to embrace a short section of transversely-disposed tubing, which thus forms a tubular crosshead D, which is engaged between the clamp- 5 5 ing-ears and through which the cross-bolt E passes. Within the rod I have provided a locking-bolt F, adapted to enter an eye 6, which runs angularly through the bolt-in the cross-bolt Eand provided with an actuating- 6o spring G for driving the locking-bolt into e11- gagement in the eye. The bolt F extends through a fixed guide or bearing H in the interior of the tube and is provided with a shoulder I, between which and the fixed bearing H the spring G is located. The bolt F is also providedwith an arm or lug J, projecting through a slot K in the rod B to permit the temporary withdrawal of the lockingbolt from the eye of the cross-bolt when it is desired to change the position of the rod.

Assuming the rod to be in its raised position, with the locking-bolt F engaged in the eye 6 in the cross-bolt E, pressure is applied to the lug J to withdraw the bolt against the tension of the spring G, and the rod is then swung downwardly to the position in which it is shown in Fig. 1, when the bolt automatically enters the eye from the lower side and holds the rod in that position. As the eye runs angularly through the bolt E, the rod B is held in a vertical position when up, but projects laterally when down, thus furnishing an efficient brace. When it is desired to raise the rod, the bolt is withdrawn from the eye in the same manner as above explained and the rod swung to its raised position, the bolt then automatically reentering the eye on the upper side and holding the rod in a vertical position. To prevent the cross-bolt E from turning, I have provided the same with a keyflange 0, adapted to enter a corresponding channel or recess in one of the ears of the clamp A.

In order to prevent the rod from vibrating or rattling against the bicycle-frame, I have provided the cross-bolt L of the bicycle-frame with a washer M, having an offset lip N, behind which the rod B is adapted to be engaged when in its raised position. The rod is swung I00 laterally to a slight degree in order to engage it behind the washer, and when engaged the tension of the parts holds it rigidly in position. By the use of this washer the locking mechanism may,if desired, be dispensed with, as the rod will be held by the washer rigidly in its raised position, and when provided with a rubber tip it is not likely to slip when used as a brace.

I attach great importance to the combination of the support with the saddle-post rod of the bicycle-frame, as the bicycle is much more adequately supported thereby than if the support were combined with any of the other frame-rods, and the rod when not in use is held in an upright position by an extremely simple device, such as the washer. M.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with the saddle-post rod of a bicycle-frame, of a clamp adapted to be secured thereto, a tubular rod provided with a tubular cross-head at one end, across-bolt for holding said clamp and cross-head together, said bolt having an eye therein, and a key engaging a recess in the clamp, and a springactuated locking-bolt located within said tubular rod and adapted to engage in the eye of the cross-bolt at either side, substantially as described.

In testimony whereof I have hereunto set my hand and affixed my seal this 24th day of August, 1898.
